Frewitt—Milling & Sieving

NanoWitt-Lab Nano Mill


The nano mill is ideal for processing batches of milligrams of solids up to 1.5kg, specifically engineered for wet nano milling of pharmaceutical products down to D50 of 50 nanometre.  Short milling times at lower specific energy allows a gentle product processing and a tight particle size distribution.

The compact design provides quick and easy setup and integration into any laboratory.

Nano Mill Product Highlight

  • High efficiency mill operating at low rotor tip speed
  • Intensification of comminution process, 
high mixing and homogeneity
  • Dynamic separation system (patented) with no filter and thus no clogging
  • Optional in-line & real-time PAT solutions for size measurement
  • GMP design combining simplicity of use, efficient beads handling and high product recovery
  • Easy cleaning Washing-in-Place (WIP) and quick tool-free access to internal components
  • Multiple operation modes (batch, semi-batch for filling/ emptying, external recirculation)
  • Simple and easy integration of the milling head into a rigid or flexible isolator
  • Very broad scope of application for all types of powders
  • Milling head readily interchangeable on a single Tri-Clamp
connection flange
  • Light, compact milling head
  • Quick, efficient and simple cleaning of the milling head 

Nano Mill Process Characteristics:

  • Particle Size Range – D50 down to 50 nm
  • Batch Size – From milligrams up to to 1.5 kg of solids
